Zosteriform metastasis: case presentation and review of the literature.

In contrast to benign tumors, malignant tumors, by definition, are characterized by the potential of giving rise to metastases. Albeit infrequently, skin metastases do occur, and their clinical appearance varies over a wide morphologic spectrum. We present the case of a 65-year-old male with zosteriform metastasis secondary to bronchogenic adenocarcinoma. A review of cutaneous metastasis is presented with emphasis on dermatomal distribution and possible mechanisms of dissemination.
